Statistical Metadata Analysis of Mobile Phone Communications

It is common in industrial countries that everybody owns at least one mobile phone or network card for connecting to a mobile (wireless) network. What is more, there are not only people. There are devices connected to networks and communicating together, which opens many new possibilities in each area of everyday life, also known as Industry 4.0. Machines and people produce a lot of data, also called Big Data. By collecting and analyzing metadata about mobile communications, it is possible to improve different services provided by telecommunication companies or improve infrastructure itself. Some existing solutions are described in our work. We tried to combine two approaches, visualization of data and statistical analysis and based on that, we have proposed, implemented, and tested a new tool, which can help data analysts in the future.
